Although not shown in FIG. 3, the other end of the electric wire 160 is connected to the light source unit 100.

  FIG. 4 is a block diagram illustrating a partial configuration of the lighting fixture 1 according to the first embodiment. As shown in FIG. 4, the light source unit 100 includes a light source unit 101 and a lighting control device 102 that turns on the light source unit 101. The lighting control device 102 includes a lighting circuit that generates DC power for lighting the light source unit 101 from the power of the commercial power supplied from the power terminal block 131, a control circuit that controls the lighting state of the light source unit 101, and the like. Prepare.

  The control unit 400 is connected to the lighting control device 102 of the light source unit 100 via the electric wire 160. The control unit 400 controls the lighting state of the light source unit 101 via the lighting control device 102. The lighting control device 102 controls the lighting state of the light source unit 101 in accordance with a control signal from the control unit 400. The control unit 400 includes a control board 401 having a control circuit, a sensor module 402, a signal input unit 403, and a switch 431 that can be manually operated from the outside of the control unit 400. The signal input unit 403 is connected to a signal terminal block 132 installed in the instrument main body 300 via an electric wire 170.

  The sensor module 402 in the present embodiment corresponds to a human sensor that detects whether or not a person exists within the detection range. The sensor module 402 in this embodiment corresponds to a radio wave sensor that transmits and receives radio waves such as microwaves. The sensor module 402 transmits radio waves within the detection range. The radio wave is reflected by an object within the detection range. The sensor module 402 receives the reflected wave. When the object reflecting the radio wave is moving, a change in frequency according to the moving speed of the object occurs between the transmitted radio wave and the received radio wave. According to the sensor module 402, a person can be detected using the frequency difference between the transmitted wave and the reflected wave. That is, according to the sensor module 402, a person can be detected using the Doppler effect.

  The sensor module 402 corresponds to a signal receiving unit that receives a signal from a space outside the lighting fixture 1. The sensor module 402 receives the radio wave reflected by the object within the detection range as a signal from the external space.

  In the example shown in FIG. 4, the signal device 900 for the guide light is connected to the lighting fixture 1. An electric wire 910 that transmits a signal from the guide light signal device 900 is connected to the signal terminal block 132. For example, a commercial power supply of AC 100V is connected to the signal device 900 for the guide light. The guide light signal device 900 is connected to the automatic fire alarm facility 920. The guide lamp signal device 900 in the present embodiment corresponds to a signal sending unit provided outside the lighting fixture 1. The signal input unit 403 of the control unit 400 is connected to the guide light signal device 900 via the electric wire 170, the signal terminal block 132, and the electric wire 910.

  In the example shown in FIG. 4, the control unit 400 receives the self-fire report interlocking signal from the guide lamp signal device 900. The self-fire report interlocking signal is a signal interlocking with the automatic fire alarm facility 920. The continuous self-fire report interlocking signal is an AC 100V signal. For example, the self-fire report interlocking signal in an emergency such as when a fire occurs is a 0V signal.

  As in the example shown in FIG. 4, the signal input unit 403 of the control unit 400 is connected to the guide light signal device 900 via the electric wire 170, the signal terminal block 132, and the electric wire 910. A mode in which the control unit 400 controls the lighting state of the light source unit 101 in response to the signal is referred to as a “first mode”.

  In the first mode: When the AC100V self-fire report interlocking signal is always input to the signal input unit 403, the control unit 400 controls the lighting state of the light source unit 101 according to the signal of the sensor module 402. At this time, for example, the control unit 400 turns on the light source unit 101 when the sensor module 402 detects a person and turns off the light source unit 101 when the sensor module 402 does not detect a person. Also good. Thus, in the first mode, a state in which the lighting state of the light source unit 101 is controlled according to the signal of the sensor module 402 is referred to as a “first state”. On the other hand, in an emergency in which the self-fire report interlocking signal input to the signal input unit 403 is 0 V, the control unit 400 is determined in advance regardless of whether the sensor module 402 detects a person. The lighting state of the light source unit 101 is controlled by the dimming rate. In this emergency, for example, the control unit 400 may forcibly turn on the light source unit 101 regardless of whether the sensor module 402 detects a person. Thus, in the first mode, a state in which the lighting state of the light source unit 101 is controlled by a predetermined dimming rate regardless of the signal of the sensor module 402 is referred to as a “second state”. In the first mode, the signal input unit 403 is connected to the guide lamp signal device 900, and the first state and the second state are switched by the control unit 400 according to the signal from the guide lamp signal device 900. Corresponds to the mode

  The luminaire 1 can also be used without connecting the luminaire 1 to a signal sending unit such as the signal device 900 for a guide light. In this case, since the self-fire report interlocking signal is not input to the signal input unit 403, the signal of the signal input unit 403 is always 0V. When the luminaire 1 is not connected to the signal device 900 for the guide light, the control unit 400 performs the “second mode” control. The second mode is a mode in which the signal input unit 403 is not connected to the guide light signal device 900 and the control unit 400 controls the lighting state of the light source unit 101 according to the signal of the sensor module 402. . In the second mode, for example, the control unit 400 turns on the light source unit 101 when the sensor module 402 detects a person and turns off the light source unit 101 when the sensor module 402 does not detect a person. You may let them.

  FIG. 5 is a block diagram showing a partial configuration of the control unit 400 according to the first embodiment. As shown in FIG. 5, the control unit 400 includes a microcomputer 404, a regulator 405, a photocoupler 406, and a signal output terminal 407. The microcomputer 404 is provided on the control board 401. A light emitting element such as a light emitting diode of the photocoupler 406 is connected to the signal input unit 403. When the luminaire 1 is connected to the guide light signal device 900, a self-fire report interlocking signal is input to the light emitting element of the photocoupler 406. The switch 431 and the light receiving element such as a phototransistor of the photocoupler 406 are connected to a circuit connecting the microcomputer 404 and the signal output terminal 407. The switch 431 is connected in parallel with the light receiving element of the photocoupler 406. The signal output terminal 407 is connected to the light source unit 100 via the electric wire 160.

  In the present embodiment, the first mode and the second mode can be switched by the switch 431. As shown in FIG. 5, when the switch 431 is turned off, the first mode is set. In the first mode: When the AC100V self-fire report interlocking signal is always input to the signal input unit 403, the light emitting element of the photocoupler 406 emits light and the light receiving element of the photocoupler 406 is turned on, so that the presence / absence signal detected by the sensor module 402 is detected. Is transmitted to the light source unit 100 via the signal output terminal 407. In this case, the lighting state of the light source unit 101 is controlled in accordance with the human presence / absence signal detected by the sensor module 402. On the other hand, in an emergency in which the self-reporting signal of the signal input unit 403 is 0V, the light emitting element of the photocoupler 406 does not emit light, and the light receiving element of the photocoupler 406 is turned off. As a result, the presence / absence signal detected by the sensor module 402 is not transmitted to the light source unit 100. In this case, regardless of the signal of the sensor module 402, the lighting state of the light source unit 101 is controlled by a predetermined dimming rate.

  On the other hand, when the switch 431 is turned on, the second mode is set. In the second mode: Regardless of the signal from the signal input unit 403, the human presence / absence signal detected by the sensor module 402 is transmitted to the light source unit 100 via the switch 431. Thereby, the lighting state of the light source unit 101 is controlled according to the signal of the sensor module 402 regardless of the signal of the signal input unit 403.

  In the present embodiment, it is possible to switch between the first mode and the second mode only by operating the switch 431, and for example, an operation of removing wiring inside the control unit 400 is unnecessary. For this reason, when constructing the luminaire 1, the first mode and the second mode can be switched by a simple operation depending on whether or not the lighting device 1 is connected to the guide lamp signal device 900. Therefore, the construction work of the lighting fixture 1 becomes easy.

  In the present embodiment, DC power generated by the DC power supply 103 included in the lighting control device 102 is supplied to the control unit 400 via the electric wire 160. This DC power is input to the microcomputer 404 via the regulator 405. As described above, the control unit 400 of the present embodiment operates by receiving power supply from the lighting control device 102 of the light source unit 100. This has the following advantages. An AC / DC conversion circuit for supplying power to the control unit 400 becomes unnecessary. The number of terminals and wires of the control unit 400 can be reduced. Power conversion loss can be reduced.

Thereby, the structure can be simplified. Each of the switches 431, 432, 433, 434 is constituted by a slide switch. Since the slide switch is inexpensive, it is advantageous for cost reduction. The switches 431, 432, 433, and 434 include operation units 431a, 432a, 433a, and 434a, respectively. When the operation units 431a, 432a, 433a, and 434a are slid, the switches 431, 432, 433, and 434 are switched.

  The control board 401 is provided with a signal input unit 403 and a wire connection unit 408. The electric wire 160 is connected to the electric wire connecting portion 408. An electric wire 170 is connected to the signal input unit 403.

  The sensor module 402 is connected to the control board 401 via a signal line 409. The first housing 411 is formed with a protrusion 420, a flange 440, an opening 441, and an opening 442. The flange part 440 forms a surface protruding like a ridge from the base of the protrusion 420 to the outer peripheral side. The opening 441 is an opening for exposing the signal input unit 403. The opening 442 is an opening for exposing the wire connection portion 408.

  A pedestal portion 443 and a rear through hole 444 are formed in the second housing 412. A groove-shaped signal line holding portion 445 and a notched slide portion 446 are formed on the pedestal portion 443. As shown in FIG. 13, the sensor module 402 is supported by a pedestal portion 443. The signal line 409 is held by the signal line holding unit 445. The control board 401 is inserted inside the slide portion 446. When attaching the control board 401 to the first housing 411, the control board 401 can be easily assembled at an appropriate attachment position by sliding the control board 401 from the upper side or the horizontal direction with respect to the slide portion 446. it can.

  As shown in FIG. 10, the operation units 431 a, 432 a, 433 a, and 434 a of the switches 431, 432, 433, and 434 protrude through the opening formed in the housing unit 410 to the outside of the housing unit 410. . The switches 431, 432, 433, and 434 can be switched by operating the operation units 431 a, 432 a, 433 a, and 434 a from the outside of the housing 410 with a finger.

  The control unit 400 includes a display unit 450. The display unit 450 displays the positions of the operation units 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 and information corresponding to the positions. By providing the display unit 450, it is possible to easily visually confirm what function has been switched to when the switches 431, 432, 433, and 434 are operated.

  On the display unit 450, self-fire report interlocking “present” and “none” are displayed as information corresponding to the position of the operation unit 431a of the switch 431. When the operation unit 431a is set to the self-fire report interlocking “present” position, the switch 431 is turned off, and the control unit 400 enters the first mode described above. When the operation unit 431a is set to the self-fire report interlocking “no” position, the switch 431 is turned on, and the control unit 400 enters the second mode described above.

  The switch 432 is a switch for switching the detection sensitivity of the sensor module 402. On the display unit 450, detection sensitivity “80%” and “100%” are displayed as information corresponding to the position of the operation unit 432 a of the switch 432. When the operation unit 432a is set to the position where the detection sensitivity is “80%”, the control unit 400 enters a mode in which the detection area of the sensor module 402 is used to detect 80%. In this mode, the detection area in which a person can be detected becomes relatively narrow, but it is advantageous for reliably suppressing erroneous detection. When the operation unit 432a is set to the position of the detection sensitivity “100%”, the control unit 400 enters a mode for detecting a person using the detection area of the sensor module 402 as 100%. In this mode, there is an advantage that a detection area capable of detecting a person is widened.

  The switch 433 is a switch for switching the standby operation of the lighting fixture 1. The standby operation is an operation of the lighting fixture 1 when the sensor module 402 is not detecting a person. The display unit 450 displays standby operations “10%”, “30%”, and “100%” as information corresponding to the position of the operation unit 433a of the switch 433. When the operation unit 433a is set to the position of the standby operation “10%”, when the sensor module 402 does not detect a person, the control unit 400 performs a process of lighting the light source unit 100 at a dimming rate of 10%. When the operation unit 433a is set to the position of the standby operation “30%”, when the sensor module 402 does not detect a person, the control unit 400 performs a process of lighting the light source unit 100 at a dimming rate of 30%. When the operation unit 433a is set to the position of the standby operation “100%”, the control unit 400 performs a process of lighting the light source unit 100 at a dimming rate of 100% when the sensor module 402 does not detect a person.

  The switch 434 is a switch for switching the lighting time after the sensor module 402 changes from a state in which a person is detected to a state in which no person is detected. On the display unit 450, lighting times “10 seconds”, “1 minute”, and “3 minutes” are displayed as information corresponding to the position of the operation unit 434 a of the switch 434. When the operation unit 434a is set to the lighting time “10 seconds” position, when 10 seconds have elapsed after the sensor module 402 changes from the state of detecting a person to the state of not detecting a person, the control unit 400 Then, the process of shifting to the standby state is performed. When the operation unit 434a is set to the position of the lighting time “1 minute”, the control unit 400 changes from the state in which the sensor module 402 detects a person to the state in which no person is detected, and when one minute elapses, the control unit 400 Then, the process of shifting to the standby state is performed. When the operation unit 434a is set to the lighting time “3 minutes” position, the control unit 400 changes to a state in which the sensor module 402 detects a person to a state in which no person is detected, and three minutes elapses. Then, the process of shifting to the standby state is performed.

  As shown in FIG. 2, the operation portions 431 a, 432 a, 433 a, and 434 a of the switches 431, 432, 433, and 434 are arranged at positions that can be operated by inserting a hand through the recess communication opening 211. The operation units 431a, 432a, 433a, 434a and the display unit 450 are located between the recess communication opening 211 and the instrument main body 300. The operator can visually recognize the operation units 431a, 432a, 433a, 434a and the display unit 450 from the recess communication opening 211.

  In a state where the light source unit 100 is detached from the first unit 700, the operation units 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 can be touched, so the switches 431, 432, 433, and 434 are It is possible to operate. In the present embodiment, the switches 431, 432, 433, and 434 can be operated by removing the light source unit 100 from the first unit 700. For this reason, when it becomes necessary to change the setting state by the switches 431, 432, 433, 434, the switches 431, 432, 433, 434 can be switched by a simple operation.

  As shown in FIG. 1, in a state where the light source unit 100 is attached to the first unit 700, the light source unit 100 closes the recess communication opening 211. In this state, the switches 431, 432, 433, and 434 cannot be operated because the operation units 431a, 432a, 433a, and 434a of the switches 431, 432, 433, and 434 cannot be touched. In the present embodiment, the switches 431, 432, 433, and 434 cannot be operated when the light source unit 100 is attached to the first unit 700. Therefore, the switches 431, 432, 433, and 434 are switched incorrectly. Can be reliably prevented.

  In the present embodiment, the direction corresponding to the left for the operator facing the luminaire 1 is “left”, the direction corresponding to the right for the worker is “right”, and the direction connecting the left and the right is This is referred to as “left-right direction”. The switches 431, 432, 433, 434 are switched by sliding the operation units 431a, 432a, 433a, 434a in the left-right direction, respectively.

  The switches 432, 433, and 434 correspond to switches that can switch specific parameters of the lighting fixture 1. That is, the parameter “detection sensitivity” can be switched by sliding the operation unit 432a, the parameter “standby operation” can be switched by sliding the operation unit 433a, and the “lighting time” can be switched by sliding the operation unit 434a. Can be switched. All of the switches 432, 433, and 434 are configured such that when the operation units 432a, 433a, and 434a are slid from left to right, the parameter to be switched increases. The horizontal axis of the graph is usually described so that the parameter increases from left to right. For this reason, it is easy for humans to understand sensuously that the parameter increases from left to right.

  The display unit 450 is behind the mounting recess 210. For this reason, when the switches 432, 433, and 434 are operated, the display unit 450 may be difficult to see because it is dark. In the present embodiment, when the operation units 432a, 433a, and 434a are slid from left to right, the parameters to be switched are configured to increase. Therefore, it is easy for the operator to sensuously understand which of the operating units 432a, 433a, and 434a is slid to increase or decrease the parameter. For this reason, even when it is dark and the display unit 450 is difficult to see, it is advantageous in appropriately switching the switches 432, 433, and 434.

  As a modification, contrary to the above, when the operation units 432a, 433a, and 434a are slid from left to right, the parameter to be switched may be configured to be small. As such, the operator may intentionally change the parameter by intentionally changing the parameter in the opposite direction.

  The control unit 400 may include a slide switch that is switched by sliding the operation unit in the left-right direction, and may be configured to be able to switch on / off a specific function of the lighting fixture 1 by sliding the operation unit. In that case, when the operation unit is slid from left to right, the function is switched from off to on, so that the slide switch is appropriately operated even when the display unit 450 is dark and difficult to see. This is advantageous for switching. As a modification, contrary to the above, the function may be configured to be turned off from on when the operation unit is slid from left to right.

  You may make it the color of the operation parts 431a, 432a, 433a, 434a and the color of the part which shows the position of the operation parts 431a, 432a, 433a, 434a among the display parts 450 differ. By doing so, the operator can more reliably visually recognize the position of the operation units 431a, 432a, 433a, and 434a. In the display unit 450, the portions indicating the positions of the operation units 431a, 432a, 433a, and 434a are portions that can overlap the operation units 431a, 432a, 433a, and 434a when viewed from the operator facing the lighting fixture 1. . For example, in FIG. 10, position display portions 451, 452, and 453 of the display portion 450 are portions that indicate the position of the operation portion 434a. In this case, the color of the position display units 451, 452, and 453 is, for example, white, and the color of the operation unit 434a is, for example, black. From the viewpoint of the operator, when the white color of the position display unit 451 is hidden by the black color of the operation unit 434a, it can be easily recognized that the operation unit 434a is at the position of “10 seconds”. Similarly, when the white color of the position display unit 452 is hidden by the black color of the operation unit 434a, it can be easily recognized that the operation unit 434a is at the position of “1 minute”, and the white color of the position display unit 453 is the black color of the operation unit 434a. When it is hidden, it can be easily recognized that the operation unit 434a is at the position of “3 minutes”.

  You may comprise so that each operation part 431a, 432a, 433a, 434a of several switch 431,432,433,434 may have a mutually different shape or dimension. For example, the operation units 431a, 432a, 433a, and 434a may be configured to have different projecting lengths. By doing so, even when the operation units 431a, 432a, 433a, 434a and the display unit 450 are dark and difficult to see, the operation units 431a, 432a, 433a, 434a can be distinguished by groping. Of 431, 432, 433, and 434, a switch to be operated can be easily found.

  As shown in FIG. 11, a part of the control board 401 can be visually recognized from the back surface through hole 444 that penetrates the back surface of the housing portion 410. For this reason, it is possible to reliably prevent forgetting to attach the control board 401 when the control unit 400 is assembled. Further, since the rear through-hole 444 is provided, the second housing 412 having the pedestal portion 443 and the slide portion 446 can be molded with a mold that can move in the direction of arrow A in FIG. For this reason, manufacture of the 2nd housing | casing 412 becomes easy.

  An electric wire holding part 447 and a notch part 448 are formed on the back surface of the housing part 410. The electric wire holding portion 447 is an elongated concave portion having a space in which the electric wire 160 can be stored. As shown in FIGS. 8 and 9, the notch portion 448 corresponds to a portion where a lower corner portion on the back surface of the housing portion 410 is notched. The signal line 150 can be inserted into the space formed by the notch 448.

  FIG. 14 is a cross-sectional view of the lighting fixture 1 according to Embodiment 1 cut along a plane perpendicular to the longitudinal direction of the lighting fixture 1. The cutting position in the sectional view of FIG. 14 corresponds to the center position of the control unit 400. As shown in FIG. 14, the first unit 700 has a first storage space 701 that is a space inside the mounting recess 210 and a second storage space 702 that is a space outside the mounting recess 210. A part of the light source unit 100 is stored in the first storage space 701. The light source unit 100 includes a translucent cover 104 that covers the light source unit 101. Most of the translucent cover 104 is outside the mounting recess 210. The translucent cover 104 protrudes toward the front side with respect to the decorative part 200.

  A portion of the control unit 400 other than the protrusion 420 is stored in the second storage space 702. In the present embodiment, the control unit 400 is disposed in the second storage space 702 outside the mounting recess 210, so that the internal space of the mounting recess 210 can be widened. For this reason, storage space, such as an electrical component with which the light source unit 100 is provided, can be expanded. Further, the working space when operating the switches 431, 432, 433, 434 can be widened.

  The instrument body 300 has a first surface 301. The first surface 301 corresponds to the back surface of the lighting fixture 1. The luminaire 1 is installed such that the first surface 301 faces an attachment surface such as a wall surface or a ceiling surface of a building.

  The mounting recess 210 is on the opposite side of the first surface 301. That is, the mounting recess 210 is in front of the lighting fixture 1. The mounting recess 210 corresponds to a first light source mounting portion that is a portion to which the light source unit 100 that is the first light source is mounted.

  The plate-like inclined portion 214 is provided adjacent to the mounting recess 210. The inclined portion 214 is inclined so as to approach the first surface 301 as the distance from the mounting recess 210 and the light source unit 100 increases. The casing 410 of the control unit 400 is stored in the second storage space 702 inside the inclined portion 214. The protruding portion 420 protrudes through the opening 212 formed in the inclined portion 214 to the external space of the lighting fixture 1. If it is this Embodiment, the housing | casing part 410 of the control unit 400 is arrange | positioned inside the decorative part 200, and the external appearance of the lighting fixture 1 is favorable because the circumference | surroundings of the protrusion part 420 are covered with the decorative part 200. It becomes advantageous in making.

  The protrusion 420 has a cover 421 that is inclined with respect to the first surface 301. The cover 421 is inclined so as to approach the first surface 301 as the distance from the mounting recess 210 and the light source unit 100 increases. The cover 421 is inclined in the same direction as the inclined portion 214. At least a part of the sensor module 402 is located inside the protrusion 420. The sensor module 402 has a surface portion 402a that faces the inner surface of the cover 421 through a space. The cover 421 covers the surface portion 402a. Radio waves transmitted from the surface portion 402a of the sensor module 402 are transmitted through the cover 421 and radiated to the external space. In addition, the reflected wave reflected by the object in the external space passes through the cover 421 and is received by the surface portion 402 a of the sensor module 402. The entire surface portion 402 a is outside the surface of the inclined portion 214. Thereby, it is possible to prevent the radio waves transmitted and received by the sensor module 402 from being blocked by the metal inclined portion 214.

  In the present embodiment, since the inclined portion 214 is formed in the decorative portion 200, the light emitted from the light source unit 100 can be prevented from being blocked by the decorative portion 200, so that a wider range can be illuminated. It becomes possible.

  The surface portion 402 a of the sensor module 402 is inclined so as to approach the first surface 301 as the distance from the mounting recess 210 and the light source unit 100 increases. By arranging the sensor module 402 obliquely in this way, the human detection range by the sensor module 402 can be further widened. The cover 421 is positioned in parallel to the surface portion 402a of the sensor module 402. Thereby, since it can suppress more reliably that the electromagnetic wave transmitted from the surface part 402a reflects in the cover 421, the detection performance by the sensor module 402 can be improved.

  In the present embodiment, the inclination angle (minor angle) of the cover 421 with respect to the first surface 301 is larger than the inclination angle (minor angle) of the inclined portion 214 with respect to the first surface 301. Thereby, since the light emitted from the light source unit 100 is not blocked by the lower end part 422 of the cover 421, the loss of light can be suppressed. The same effect as described above can be obtained even when the inclination angle (recess angle) of the cover 421 with respect to the first surface 301 is equal to the inclination angle (recess angle) of the inclined portion 214 with respect to the first surface 301.

  The flange portion 440 of the control unit 400 is in contact with or close to the inner surface of the inclined portion 214 at the periphery of the opening 212. The surface of the flange portion 440 is inclined with respect to the first surface 301 so as to be parallel to the inclined portion 214.

  In the following description, a direction perpendicular to the first surface 301 is referred to as a “first direction”. A cylindrical figure 950 indicated by a broken line in FIG. 14 corresponds to a virtual cylindrical figure composed of a locus obtained by translating the edge of the opening 212 in the first direction. The cylindrical figure 950 is a rectangular cylinder. In the present embodiment, the entire protrusion 420 is located inside the cylindrical figure 950. This has the following advantages. FIG. 15 is a cross-sectional view showing a state before the decorative part 200 is attached to the appliance main body 300. The cutting position of the cross-sectional view of FIG. 15 is the same as that of FIG. The control unit 400 is attached to the instrument main body 300 before attaching the decorative part 200. When attaching the makeup part 200, the makeup part 200 is brought close to the instrument body 300 with the makeup part 200 facing the instrument body 300, and the makeup part 200 is combined with the instrument body 300. When the decorative part 200 is combined with the instrument main body 300, the protruding part 420 needs to be inserted into the opening 212. According to the present embodiment, the protrusion 420 can be inserted into the opening 212 by moving the decorative part 200 in the first direction with respect to the instrument body 300. Therefore, the decorative part 200 can be united with the instrument main body 300 by an operation of moving the decorative part 200 in the first direction with the decorative part 200 facing the instrument main body 300. For this reason, the operation | work which attaches the decoration part 200 with respect to the instrument main body 300 is easy, and the said operation | work can be implemented easily and rapidly.

  Furthermore, according to the present embodiment, the size of the opening 212 can be made substantially the same as the size of the base portion of the protruding portion 420. That is, the size of the opening 212 can be made substantially the same as the size of the protruding portion 420 at the position of the surface of the flange portion 440. For this reason, the clearance gap between the opening 212 and the protrusion part 420 can be made small. On the other hand, when the makeup part 200 must be moved in an oblique direction when the makeup part 200 is attached to the appliance body 300, the size of the opening 212 is made larger than the size of the root part of the protrusion 420. It needs to be large enough. With such a configuration, the gap between the opening 212 and the protrusion 420 cannot be reduced.

  The surface of the flange portion 440 corresponds to the boundary between the housing portion 410 and the protruding portion 420. As shown in FIG. 14, the protruding portion 420 in the present embodiment has a wall portion 423 that connects between the cover 421 and the flange portion 440. The wall part 423 protrudes from the flange part 440 along the first direction. The wall portion 423 is located along the portion of the edge of the opening 212 that is closest to the first surface 301. In the present embodiment, by providing such a wall portion 423, the internal space of the protruding portion 420 is sufficiently increased while the entire protruding portion 420 is positioned inside the cylindrical figure 950. be able to. For this reason, the space which arrange | positions the sensor module 402 can be enlarged.

  Although the first embodiment has been described above, the present invention is not limited to the above-described embodiment. For example, the signal sending unit may be an automatic fire alarm instead of the guide light signal device 900, or may have a configuration in which the automatic fire alarm and the guide light signal device are connected. Further, the signal input from the signal sending unit is not limited to AC 100 V, and may be a dimming signal sent from a guide light signal device, for example.

  The signal receiving unit is not limited to a radio wave type human sensor such as the sensor module 402, but may be an infrared human sensor that receives infrared rays emitted from a human body as a signal from an external space, It may be a brightness sensor that receives the amount of light in the space as a signal, or may be a light receiving unit for a remote that receives electromagnetic waves emitted from the remote as a signal from the external space. In addition, the switches 431, 432, 433, and 434 have been described by taking a switch having a slide type mechanism as an example, but instead of this, for example, a switch having a push button type mechanism may be used, or a needle Or you may use the switch which has a mechanism which inserts another tool and performs switching operation. Further, the plurality of switches 431, 432, 433, and 434 may not be unified to have the same type of mechanism, and a plurality of types of mechanisms may be mixed.
